Outline of Final Research Achievements |
Blood is a dense suspension of red blood cells (RBCs), and RBC behaviors strongly affect mass transport of blood flow. Thus, we need to consider micro scale RBC motions when we discuss the mass transport of blood flow. However, in many cases, blood was assumed as a homogeneous liquid in former studies. Then, we need to develop a completely new continuum model of blood, which is based on cellular scale RBC behaviors. In this study, we developed a computational model of red blood cells using a finite element-boundary element coupling method, and by using the developed RBC model, we calculated a particle stress tensor and shear-induced diffusion of red blood cells in order to develop a new continuum model of blood.
